Best way to save user info/settings?

I'm writeing a vb.net program where I would like to save users login/passwords/phonenumbers and stuff so they don't have to re-enter them each time.
What would be the best way to accomplish this. I'd like to write/read them from a file of some sort such as an XML file or .ini file and would like to stay away from using an access database.

What is the industry standard/common way to do this?
How would I create the file and save information to it, read it, AND be able to re-save to it, like if a users password changes etc.

Thanks for any advice or code examples :)

Hi Matrix1000,

How secure do you want this to be ?

it doesn't have to be secure

Hi Matrix1000,

In that case I would write a small class with the information I want to keep and use a soap or binaryformatter to serialize it to an xml file. If you would like I could write some example on how to do that.

THANKS!!!!!!!!!!!!!!!!!!!!!!!!!
How would I read the saved settings?
Is reading the settings as easy as.......

Private Sub Button2_Click()
Dim x As New mysettings()

'loads the xml document
x.LoadXML("c:\test.xml")

'makes the login and pass fields show the saved settings
txtlogin.Text = x.Login
txtpass.Text = x.Password
End Sub

RonaldBiemans

Yep, it is that easy

hmm the saving part works GREAT! but I cant seem to figure out how to read the data again...the example below doesn't work right; the textboxes don't fill in

'loads the xml document
x.LoadXML("c:\test.xml")

'makes the login and pass fields show the saved settings
txtlogin.Text = x.Login
txtpass.Text = x.Password

What does the file contents for c:\test.xml look like?

That's a curious thing, because the XML file has the necessary contents.

Sorry Matrix1000, my mistake, it should be

Dim x As New mysettings
x = x.LoadXML("c:\test.xml")
TextBox1.Text = x.Login
TextBox2.Text = x.Password

RonaldBiemans

You can also remove the new like,

Dim x As mysettings
x = x.LoadXML("c:\test.xml")
TextBox1.Text = x.Login
TextBox2.Text = x.Password

Bob Learned

That's interesting, because the first comment was:

Dim x As New mysettings()

'loads the xml document
x.LoadXML("c:\test.xml")

'makes the login and pass fields show the saved settings
txtlogin.Text = x.Login
txtpass.Text = x.Password

and the second was

'loads the xml document
x.LoadXML("c:\test.xml")

'makes the login and pass fields show the saved settings
txtlogin.Text = x.Login
txtpass.Text = x.Password

I missed the missing 'Dim x As New mysettings()' line.
